however, since thel form no lpart of the in' .ventioninissua ut vthe elevator shaft isv shown at Wone end of which is carried in a bearingX removed some distance from said elevator, said shaftbein driven by means of` a belt Y and pulley'Z. n the shaft between the pulley land. the said bearing yX is an eccen-v tric Shaving an eccentric'strap 2 .forming art.y oa piston and pistoiie'rod 4, Fig. 6, i ounted on the side of the body A is a cylin- -der bymeans of'members 6 which alloWa y sliht pivotal movement, and within said cyli er he piston 4 is desi ned Ato have-vertical' Another Ypipe connects .the pipe il with the vtank '7 as infflicated b which will noivbe described.

in operation aloaded wagon is driven upon the platform orboily A so as to place itsiront wheels upon the member E, its rear ,end f.verliangi'iig; itlic cuiiveyer U'- as in coinmoi'i practice.' The elevator bein r in o erm tion Y i' g bem-tr driven 'from the cel- 1 dc io' the piston fi ci lic puiilp 5 to draw oil from the ltank T aiiil vl'oicc it intl ffii-l pipe 9 this being pessime by theplacng cia checksy valve il in the pipe and' one in said pipe 9 indicated at l2 sa il vulves boing constructed and. arranged Ywlirireby cilnmy pass through;

cannot. return therethrough und so tliiit oil cmi be foi-'ced into the pipe-li toward the i-vl ludo!" (i but cannot return to the pump. The continuous operation oi thc pump, therefore, transfers tlicoil from the tank 7 to tlic cylindex" (i thereby causing tlic piston J oi tlic i0 the purpose of` 1 scopes latter 'to be elevated with the result that thev member Eis raised on the derricks by means of the rod N on the crossehead .Land the cable P, it being seen that said cable imparts a raising movement to the vlatiorm corres ending to that given by said rod N.- This e evates the front end of the wagon so as .to dump the load into the conveyer U. When the cross-head reaches a point near the end of its upward travel it meets a lever 13 pivoted on the derrick D which has connection by a rod 14 with a cut-off valve 15 in the p1 e 8. The said lever is raised to move said va ve 15 to stop the flow of. oil to the pum 5 .and the latter, though running continuous y,

in being deprived of oil can raise the member, E no higher and said member must remain at rest until theoperator is ready to lower the Wagon after it has been completely unloaded.

'To accomplish the lowering movement he gras s a lever 16 pivoted near theelevator and y pushing it toward the derrick opens a valvel' in the Weight of the inem er E and the Wagon are upontlie oil in the vcylinder G that fluid is under pressure but it cannot return to the ump 5 by reason of the check-valve 12 be-i ore mentioned. y' li-IoWever, when the valve 1.7 is opened by thelever l16 the oil is freeto vreturn to thetank 7 from. which it came.

The vragen is thus allowed to fall to its nor mal osition and can' then be removed from the p atform 'and having reached this normal positionA the lever is released' and a s ring 16al connected thereto returns it to its rst posi.- tion thereby closing the valve 17; tlievalve .15 the while, remaining closed until a loaded ipe 410. .`NoW since the.

Wagon is again placed in position for dumpfing at which time 'the operator grasps a second lever 18 adjacent to the lever 16 which has connection with the rod 14. and by a movement thereof raises said rod toopen the valve 1-5. The oil is then immediately drawn into the pump 5 kand the member E is again started upward.v Fig. 1a shows the connection for the movement of the valve 1 5 by the lever .il rod 19 (see also`Fig. v1) connects the said lever 4 with a bell-crank lever 20 pivoted cn the derrck D the said lever'20 being'slotted at 2l for receiving a pin 22 in the rod 14. lt'Will be seen that amovement of the rod caused by the cross-*head Will raise the bell-crank lever and also the lever 18 Willibe shifted on its pivot,'while amovement of the lever 18 by hand will move said rod as well as they valve 115." lt isv at once evident that the valve 17 .han be opened just enough to permit thc wagon to lower very slowly or by a full opening it may be lowered micli faster than it was raised by the pump thus giving the op? erator perfect control over it. in Fi' 'si 'l and 4 the system oi' 'iiiing and the va ves are clearly illustrated flint in the other figures these parts have been 'climinatedin order that qthose figures may be moreeasily read l and understood. The pump is allowed 'a l the wagon is to be slight pivotal-movement to permit the piston to lmove with the eccentric there being sufficient length of the pipes to permit them to swing with the cylinder, though there are other methods that could be provided as Well as this for permitting free movement of the pump since l do not confine myself to this structure and, in fact, it is not my purpose to hold myself to vthe exact construction shown in the drawings as to any of the arts as many changes may be made that wil still be within the meaning of the invention and its claims. lThe piston J can, of course, be

made to oierate in the reverse order from that described by pumping the fluid into th top of the cylinder instead of the bottom and this would require the rearrangement of the cable and pul eys.

It is to be observed that the wagon is raised slowly for the reason that the amount of fluid pumped at each stroke is quite small as compared with the capacity of thecylinder G, and further it will be seen that in opening the valve 17 fully the oil can return quickly to the tank 7 thereby lowering the wagon much more quickly than it is raised. As al matter of fact, the wagon should 1preferably rise slowly so that its contents wi not pass out too rapidly otherwise the conve er would become overloaded. When unloa ed rotten out of the lway'as soon as possible and this is done by allowing the oil to escape into the tank 7 at once. The latter mem er may be made of any form and size and placed anywhere out of the wa f of thewagon.' lThe guides KK on the derric D serve to keep the piston-rod H in line with its cylinder Gand also relieves the .strain occasioned by the pull of the cable and the rod N on the cross-head.

Any other form of the member Emay be used in preference to that described and shown' or any other means can be em loyed by' which to raise the wagon throug my hydraulic lifting means. As herein-before ist stated I do not confine myself to the use of the Wheeled platform A, necessarily, since any portable member. may be used by which the various necessary parts can be trans orted.

It is to be observed that the derric s D in being slanted or inclined cause the wagon 'to be raised in such a way that its rear end is shifted but little where it overhangs the conveyer so that there can be no danger of spilling rain outside said conveyer. lf the mem er E were moved vertically the spilling of grain would result since the wagon in raislring would be made to advance and recede accordin to Whether it is raised or lowered and its 'r elivery end would shift to such an extent thatthe grain would be lost. This may be better understood when it is stated that the line of movement of the member E Y the arc of a circle.

pump an be parallel to a line extendin from the' center of the frontaxle When at its cwest position, to the same oint Iat the raised position. 'In-other words, sup osing the wagon to be tilted 'upward using le rear aide as a pivot the front axle will' describe a athin Nowa line drawnt rou h the lowest and hi hest point reached by t 4e said front axle wi lbe parallel ,to the angle at which the derricks are placed. Moved thus the delivery end of the wagon would have a very slight movement indeed or one such as to cause no trouble of the kind mentioned'.

With regard to the pump it is evident that this member may be arranged to be stopped,

if desired, when the wagonrlias been raised to the desired height 'for dumping instead of.

cutting volf the uidsupply and thereby accomplish the same object as when stop ing said iluid sup ly through the valve 15. vi-

`dently the va ve 15 need not be closed when the piston J is at r`est in the raised position or even when in t e actof lowering, and the normally closedvalve -17 at .the .same time can be opened very sligllritly thereby allowing the fluid to circulate t ough the pump,l the pipes and thecontainer 7 withoutaffecting the said piston J the pressure through 4the pipev9 being equal to the pressure upon the iston due` to the wei'ht ofthe wagon 'an the member E. Wh' e water or oil may be used in the mechanism, oil bein referred for'obvious reasons, yet air coul ikewise be used if desired.
